If your job involves working with computers then there will probably come a time when you need to learn how to use new or updated software. It may be that it takes you a long time to get to grips with new software and you worry that you are not going to be able to do your job properly whilst you are still new to it. If this is that case then it is worth talking to your employer and asking them if it is possible for you to have access to it early before it is rolled out to have a look around. Many companies will bring someone in to the business or send their work staff out to a training course, but if not you may just be left with a manual that you need to read through.
New software often brings with it additional functions and sometimes update security. IT is important to try and find out what advantages the new software has over the old one as you may be missing out on something that could save time and help you do your job better. There are often video tutorials online that you can also watch to find out how to use certain bits of software.
