Piffle glad you are feeling a little better, hope dd is well again soon!
Lunar, I know a little of what you're going through, albeit on a lesser level. Before I got pg, I was always in early, worked a sixty hour week, never had a single day off sick and was never late. I got pg and suddenly their attitude towards me changed. I had ten days off sick in total in the first 14 weeks of pgcy, none of them skiving, all genuine illness.
They started monitoring my calls to check I was hitting my targets, they started crawling over my clients and candidates like insects whenever I was off (because "just because you're not in, the business has to go on") even if I was just an hour late due to morning sickness, and much more.
What I did next was a massive blow to my pride. But it was the best thing I could have done. I played the pregnancy card. If ever my call rate was down, it was due to tiredness caused by pgcy. If I let a fee slip, it was because of forgetfulness due to pgcy. If I got in a row with my w*nker colleagues, it was because I was hormonal, due to pgcy.
I felt awful doing it, because it didn't square with my image of myself (strong, confident, assertive salesperson blah blah blah). But basically, your company aren't allowed to sack you for any reason related to your pgcy. So I made sure that everything I did that I previously could have been disciplined for (they're really strict) was related to pgcy.
I know they all complain about me behind my back (I have heard them) and talk about how my attitude has changed, how negative I am and how I bring the team down, but now I no longer have the fear of being sacked, I can ease up a little. I still work the 48 hours for which I'm contracted, but if I am tired, I rest. If I'm ill in the morning, I come in later. (And if I want to use calling time to go on mn, I do it, albeit secretively!)
Your job sounds a lot more "high-powered" and pressured than mine, but it seems like our bosses went to the same management school. Best of luck in trying to get at least a little rest!
