Disappointed in my employer

Kendra
Im now 36 weeks and feeling completly exhausted. I work in housekeeping at a very busy hospital that keeps me on my feet for 8 hrs a day constantly on the go; bending, lifting, cleaning, and scrubbing. I no longer have the energy to get through the day like i used to, and find it hard to even get the necessities done, let alone all the extra crap they want us to do. I asked my supervisor if i could get some help and was told i needed a drs note outlining my specific restrictions. I went through the motions and they still found ways to get around sending me some help. Im dissappointed that my supervisor is so unwilling to lend a hand and lessen my work load (which is completly maxed out to begin with). I guess ill just be working slower and not doing all the extra crap they want done!
