Your employees can claim that you are "old school" on this matter, but the truth is that they should return to their "old school" and learn how to write correctly.
Starting sentences without capitals and totally misusing or forgetting about commas, apostrophes, and periods may be passable when one is sending extremely basic data. However, when there is something of substance to be communicated, messages can be confusing, inaccurate, or muddled in some other way if the sender has a marginal ability to write properly.
For example, someone may write, "i saw your side of this matter and the companies." Not only are there obvious grammatical errors here, it is also unclear what in the world the sender actually saw. Did the writer see many companies out there, or did he or she see the company's side of the matter? Who knows?
Whether employers like it or not, poor writing is not something to write off. Left unchecked, poor writing can cause performance and productivity to be off, too.
