To think manager is taking the p*ss?

Have you actually spoken to the big boss, explaining it as it is here? Before he goes on leave, look at his diary and tell him what you can cover and what he needs to get someone else to cover.

send him emails on a Monday, copied to your big boss, with questions you need an answer to that day.

I too think you should deal with this now rather than have it get worse while you’re on leave. ‘I have x y and z to do today, I can’t cover this for you. Have cc’d manager for you to work it out with them.’ (Reply by email even if they message /talk to you- hi X you asked me to do y earlier for you, like I said I haven’t capacity, have ccd manager so you can work it out’

and if there is anything that should be shared around, hand it the fuck back around. Dear all, I’ve been doing x for a few weeks, time to share it around- joe can you do it for the next few weeks? You will have to train my cover so makes sense.’

how does he try and take credit for your work? I’d be raging about that!!

And surely if he can do this, everyone can?

Sounds like his Manager needs to start managing and stop turning a blind eye to this blatant piss take.

Surely he won’t be able to carry on doing this once you’re on maternity leave?

I’d try and flag it before you leave? State you’re concerned that as you’re struggling with the current workload (due to CF having so much time off) that cover won’t be able to maintain and that the toil CF is building every week maybe needs addressing? Easier said than done I know.

So he’s pretending to work an extra day each week and then falsely claiming back a day off each week in lieu?

surely his manager / HR would like to know this?

How is he allowed to build up one full day of toil every week?
That sounds dodgy. Does his manager know that he's doing that?

It would be like me (I work 9-5) deciding to work Saturday from home . Hes prob doing not much at home. Then building up loads of toil hours.

Surely you are only meant to do toil hours when you are asked by the company. He can't just decide to do them whenever he wants.

On Mat leave from June, with someone covering my post so I am just sucking it up now until I leave.
Dont do this (suck it up) or your cover will also do it and it will become status quo. The longer you leave it the more difficult it will be to change.

I wouldn’t complain (at first). Instead I’d request a substantial raise to reflect X% of your time you’re spending achieving higher pay grade work.

If that raise doesn’t materialise or isn’t worth it then I’d complain.

We are not allowed bank leave like that. You can't just do additional hours because you want to, they have to be approved in advance by your line manager. Our HR would have stopped him long ago. YOu need to say it to him and then you need to go to HR if it's causing you problems. But be prepared for him to be unhappy.

Did this get mentioned when your pregnancy risk assessment was done? It's the sort of thing that I would flag through that process - i was essentially told to stop work at 36w with DD2 following a routine appointment when my BP was very high (and later turned into preeclampsia). Working so much extra is bound to put extra stress on you and isn't sustainable as you start to hand over to your cover. Could you raise it in the context of needing your risk assessment to be reviewed as you are starting it find it all difficult? How many weeks will you be when you finish?

What's the policy on accruing toil. You need to direct work you can't cover to his senior and hopefully they will address this.

Personally I’d do it before maternity leave as the cover is only short term and maybe they’ll be able to just cover him because after all it’s only temporary. This may make it worse for you as if you try to address it then they may say that you never said anything before your newborn and even the cover had no issues so they may twist it to the fact that it’s you and the only thing this changed is you now have a newborn and it’s he fact that you’re now working less effectively!

The key here is most place only allow such personal adjustments if it meets business needs well obviously given how small the team is, it patently doesn’t. However, if you’re picking up the excess then this fact is being disguised. So please just do only your only direct work and once deadlines are not being met then it will need to be addressed and his ridiculous working pattern/preferences will naturally come into question without you having to directly dog him in as it were.

Surely they can see he’s taking the piss. ‘Admin work’ hmm, is there proof of this via teams etc?

When do you start maternity leave?

Well surely you’re off on maternity leave soon and it’ll soon appear that they’re fucked without you and it’ll get sorted in your absence.

You really need to tell him no when he asks you to pick up his work. If you've too much of your own then you can't do his as well. His leave is his manager's concern, not yours, but don't agree to the extra work.

This.

Stop doing it.

When he's off. don't cover it.

When it gets flagged - as above...

I cannot cover your work as well as my own, I do not have the capacity. If you want to de-prioritise some of my work then let's get that documented on email and I'll cover what you prioritise but I'm not doing your job and mine.

Oh BTW, I've been working extra hours too, so this TOIL, I'm presuming it's available to us all, not just you? Let's clarify that too.

What will happen when you go on maternity?

Say he needs to arrange those matters on the days he's not on leave. Stick to the word no, you can't beause you have other work commitments.

I'd ask your HR department what their policy is on accruing overtime to be used as additional leave.....

Yes, you need to stop picking up the work. Explain you're fully at capacity and cannot cover. Ensure he makes arrangements to work his leave around his commitments. Keep discussing. Keep not doing his work. Let him and other manager deal with the fall out. Keep doing this until it causes enough of a problem for bigger manager to deal with.
