At my job all employees are required to be on walkie with earpieces in their ears at all times. They are awful, they basically clip onto our ears and has an earbud that sits in. It's super uncomfortable especially if you are working an 8 to 10 hour shift.
I was talking to my boss and didn't realize I had forgotten to put it back in and he asked why I wasn't wearing it. I said it's uncomfortable and if there was anyway I could have the walkie without? He said absolutely not, that is against policy and he wears his all day and he doesn't like it but it's not uncomfortable and that next time he sees me without the earpiece in he is writing me up.
