OK, I'll bite. A one-liner it is:
$ cat test.tsv
id name position
1 Nick boss
2 George CEO
3 Christina CTO
$ perl -MText::CSV_XS=csv -E'my$aoh=csv(in=>"test.tsv",bom=>1,sep=>"\t
+");' \
-E'for$h(keys%{$aoh->[0]}){say$h;open$fh,">","$h.txt";say$fh $_
+ for$h,map{$_->{$h}}@$aoh}'
id
position
name
$ cat id.txt
id
1
2
3
$ cat name.txt
name
Nick
George
Christina
$ position
boss
CEO
CTO
update: added a -E to split the line for readability
Enjoy, Have FUN! H.Merijn

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

Want more info? How to link
or How to display code and escape characters
are good places to start.
