Worried I'm not a good employee

[myear]

I am overworked and underpaid in my job. I have been raising this for a few years, asking for additional resources and a pay rise. Both have been denied on the basis that I should be able to manage my work and I am paid enough. I am not happy so have found another job and resigned, but have since found out that I am being replaced by two people and the salary on offer is higher! The advertised jobs are the same as what I do.

Is this a negative reflection on me? My new job is a step up so this is denying my confidence that I will do a good job. Surely if I was doing a good job I would have been offered the higher salary and they would have recognised they need more people in the team.

So you were doing the work of two better-paid people, and that's making you feel you were inadequate? Your old job were taking advantage big time all along and now you've called their bluff they're having to pay what they should have from the start.
You should feel good about yourself and furious about the way they treated you

I was in your position.

It's disappointing but a lucky-escape long-term.

Enjoy your new job!!

So they knew you should have been paid more but were happy to get away with paying you less for so long . Now they have realised they can't replace you on what they paid you ! How cheeky of them ! Enjoy your new job , good luck

but have since found out that I am being replaced by two people and the salary on offer is higher!

I think this is more common than people think and it's awful.

It's usually borne out of them looking to readvertise, realising not a single person will apply, then raising the wage to what it should be. Then they think "the new person will leave as its too much work, better make two posts".

They fail to realise that if they paid you the proper amount, they could probably get away with a second person part time and also retain your knowledge

They are idiots. And a lot of employers are.

Definitely not. It reflects the fact that what you were telling them was spot on. In fact you were an amazing employee to do it for so long.
Sadly not uncommon in my experience to only realise how much people are doing & how valuable they are once they are not doing it and business has to go external market rates to hire.

It's not a negative reflection on you.
They knew you were doing the work of two people.
Your manager will have had to justify why they've had to recruit two people when one person is leaving.

Nope, you're taking the wrong message from it. This has happened to me twice. I was working exceedingly hard, and hadn't seen a pay rise. Every time I went on mat leave I got replaced by a small team.

It means you've been doing the job of more than one person and they were getting you cheaply too. You've absolutely done the right thing getting a job elsewhere as they clearly didn't appreciate you properly.

Thank you all, that makes me feel better! They didn't even try to hire a like-for-like replacement - as soon as I handed in my notice the first advert they put out was for 2 people, it's like they have always known what I was doing would be hard to get in the market. Part of the reason I started looking for a new job was because when I raised the issues, they said they were actually considering making my role redundant - maybe to get me to stop complaining?

I am perhaps being naive but it feels like I wasn't good enough for them to raise my salary and hire someone else - it's so much more hassle and costly to rehire but it seems they would rather do that than keep me.

I've just left a job for similar reasons. I was doing all the work and others in the team doing very little. I hope they realize now I'm gone how much I actually did. In fact I only left last week and I think the shit will be hitting the fan already. I would be enjoying hearing of the ensuing chaos if I didn't know that it will be the clients that will suffer.
