A year ago I started a new role, it's an admin/ project support type role for a small company, I am a shared resource basically for everyone. The pay is pretty crap tbh (£20k!!) but the company is nice and I get to WFH full time so for me it negates the crap pay.
Due to the small nature of the company and the way it is structured, I am the only person who isn't commission based. Over the past 6 months the company has done really well (which I am pleased about, I think when it's a small company it feels more like a family so you naturally feel the highs and lows more, it also obviously means our jobs are more secure) and workload has increased fairly dramatically. We have grown in terms of staff and so more and more work is being piled onto me.
I am pretty much drowning in work all day, everyday now, I do take my hour's lunch each day because it's my only opportunity to walk the dogs in the daylight atm and I enjoy the fresh air and exercise, however there's so many days where it's gotten to 4pm and I realise I haven't even been to the toilet or even made a cup of tea all day.
We are winning a fair few projects atm and this is always met with whoops of joy from everyone else, with them exclaiming how much money each project has brought to the company and of course, they're all getting commission on this so of course they're all happy. I chime in with a 'woohoo, that's brilliant.' every now and again but inside I'm resentful as I think it's all a bit tone deaf and insensitive of them considering they know that I'm the lowest paid person in the company and all extra projects mean for me is more work with no additional pay.
My boss mentioned last week about hiring another me (which we do need and will especially need in the coming months) but I have no idea who is going to manage this person, I except it'll fall to me.
Don't get me wrong, I know I took the role at X amount salary, but there is no room for progression unless I want to do sales (I don't) or get an engineering degree to do more on projects (I don't!) The problem is I'm 10 weeks pregnant and haven't told work yet 
so I don't feel like I can really discuss progression in the company, at least not for the next year.
Ideally I want a bit of a payrise as I've busted my arse off like everyone else for the last year and yet I'm the only one who hasn't seen any compensation for it. But again, I'm about to tell them I'm pregnant in the next few weeks, I don't think it'll go down well even though I plan to return full time after 9 months so hardly feel I can ask for a payrise.
AIBU/ an entitled brat? Feel free to be honest as i'm half thinking I just need to get over myself but the other half is starting to feel really resentful.
