OK so 2 questions - am I being unreasonable and WWYD
Started a new job post maternity leave doing 4 days a week. Colleague sitting next to me is also new, let's call her Z. Only 5 weeks in and I am already tired of the "oh you're so lucky to be part-time" and "I'd love to have a day off a week to lounge around" comments from her. She has no DC so to her a day at home with a 2 year old appears to involve lying on the sofa watching daytime TV. Am a lone parent so I have to pick my DC up at 6pm from nursery so leave at 5 but I take my laptop home, work every night once DC in bed for an hour or two, don't take lunch generally (went to lunch for the first time last week) and am on my blackberry in the mornings before I reach the office at 9. The job was advertised as part-time as 3 or 4 days and from the spec it seemed to me it was at least 4 days which I chose to do. In reality it is a full-time position and so you just have to pack in as much as possible. I like the job, am paid well, and like the people so no violins necessary and I know everyone working with kids has these pressures and we all cope.
Anyway...have been letting the oh you're so lucky comments wash over me until this past week, sickness has spread through the office like wildfire and people have been taking days off to recover. I've now succumbed but not had any time off work with it because chicken pox is circulating at nursery and am terrified am going to have to take time off work for that so am just dosing myself up. Z has had 3 days off sick in the past 5 weeks for 2 separate illnesses (she started 1 week before me). So another colleague says to me, you're doing well to be in the office (she herself had been off with this same thing for 1 day) and I explained re pox scare and Z pipes up with well you had a day off already this week to be sick (meaning my non-working day) and I said no I haven't and she wanted to argue that my non-working day was in effect my sick day. I just quietly pointed out I don't get paid for not working that one day a week and you do get paid if you take a sick day and left it at that.
So before I get further annoyed by this (a) am I being oversensitive to get so riled by this? (have history of workplace bullying pregnancy & mat leave related so realise I have ishoos) and (2) if not, how can I nip this in the bud in a polite but firm way?
Incidentally, Z is orthodox Jewish and leaves every Friday at 1/2pm to get home before sundown for Shabbat. I would never ever say anything about how lucky she is to leave early because it would be totally inappropriate because to her it is as non-negotiable as me needing to pick my DC up and all I have ever said when she goes is "Shabbat Shalom" (I get oh you're so lucky to leave on time EVERY FRICKIN" NIGHT as well).
Oh and we do not do the same job - I am the only person that does my job so there is no scope for her ever having to pick up any of my work for me. It will just pile up until I get to it.
